    摘要： A material removing tool, wherein a rotary carrier supports several holders for discrete blades each having an elongated cutting edge and a rear edge which is parallel to the cutting edge and abuts against a shoulder of the respective holder. The end surfaces of each blade have triangular notches for pins which are provided on the respective holder and one of which is biased toward the other pin by a helical spring. The pins thereby bear against inclined cam faces which bound portions of the respective notches and cause the rear edge to remain in abutment with the respective shoulder. A blade can be removed after the movable pin is shifted away from the other pin.

    摘要翻译： 一种材料去除工具，其中旋转载体支撑用于分立叶片的多个保持器，每个保持器具有细长的切割边缘和与边缘平行的后边缘并抵靠相应的支架的肩部。 每个叶片的端面具有用于销的三角形凹口，销钉设置在相应的保持器上，并且其中一个通过螺旋弹簧朝另一个销偏压。 因此，销钉抵靠倾斜的凸轮面，该倾斜的凸轮面限制各个凹口的部分，并使后边缘保持与相应的肩部邻接。 可移动销从另一个引脚移开后可以拆下刀片。

    摘要： A locking structure for locking a cutting insert to a tool holder, the insert having a generally hour-glass shaped lockscrew receiving aperture therethrough. The lock-screw is provided with a head having a lower section which flares outwardly from the shank, a central cylindrical section and an upper section which converges in generally frusto-conical fashion. The axis of the lock-screw receiving aperture in the tool holder is slanted toward the plane or planes of one or more locating abutments on the holder. The components, when assembled, provide a positive lockdown for the insert in the tool holder, force the insert positively against the locating abutment or abutments and, yet, permit the insert to be removed without complete removal of the lock-screw.
